Zusammenfassung: | To produce a centrifugal compressor wheel assembly that can be employed in devices such as turbochargers or employed as a component of mechanisms requiring a compressor wheel assembly.SOLUTION: A compressor wheel assembly 10 includes a tubular insert 12 with a compressor wheel member 16 connected thereto which engages a shaft, and a turbocharger including the compressor wheel assembly. The tubular insert has a wall member defining a shaft bore that extends from an inlet end to an opposed outlet end. The wall member has an outer circumferential surface and an opposed inner circumferential surface. At least one engagement member may be defined on the inner circumferential surface. An engagement member may be defined on the outer circumferential surface. The tubular insert can be composed of a suitable metal.SELECTED DRAWING: Figure 1
【課題】ターボチャージャのような装置に使用されるか、または圧縮機ホイール組立体を必要とする機構の構成要素として使用され得る遠心圧縮機ホイール組立体を作る。【解決手段】圧縮機ホイール組立体10は、シャフトと係合する圧縮機ホイール部材16が接続された管状インサート12および圧縮機ホイール組立体を含むターボチャージャを含む。管状インサートは、入口端部から対向する出口端部まで延長するシャフトボアを形成する壁部材を有する。壁部材は、外周面と対向する内周面を有する。少なくとも1つの係合部材は、内周面上に形成されてもよい。係合部材は、外周面に形成されてもよい。管状インサートは、適切な金属で構成されてもよい。【選択図】図1 |
